If you're hypothetically caught talking to yourself in public and wish to provide an explanation that doesn't draw too much attention or raise concerns, you can use a light-hearted and relatable excuse. Here are a few hypothetical excuses you could consider:
Pretend you were on the phone: Quickly take out your phone and act as if you were having a conversation with someone on the other end. Say something like, "Oh, sorry, I was just finishing up a call."
Humorously blame forgetfulness: Jokingly say something like, "Oops, I guess I was rehearsing a speech, but it seems I forgot to turn off the 'out loud' mode."
Act like you're talking to a pet: Smile and say, "Oh, I was just talking to my dog/cat in my head. Sometimes it just slips out."
Pretend to be talking to an imaginary friend: Playfully say, "You know, I've had this imaginary friend since I was a kid. Guess I got carried away."
Blame it on a song or podcast: Point to your earphones and say, "I was listening to this podcast/song, and I couldn't help but react out loud."
Attribute it to self-reminders: Explain, "I tend to talk to myself to remember important things. It helps me stay organized."
Apologize and attribute it to thinking aloud: Say, "Oh, my apologies. Sometimes I think out loud without realizing it."
Remember, these excuses are meant to be light-hearted and not meant to deceive anyone. People talking to themselves in public is not uncommon, and most often, others won't think much of it or may even find it relatable. However, it's essential to gauge the situation and use your judgment when responding to any questions or comments that may arise.
